我国资产价格波动与货币政策关系研究

随着金融自由化的逐步推进,资本市场存量日益增大.这既体现了金融深化程度的提高,又意味着货币供应与国民经济主要指标之间稳定性的弱化.资产价格对货币政策的制订和执行会产生深刻的影响.其中股价、房价等资产价格在货币政策传导机制中扮演的角色越来越重要.本文从实证角度出发,通过构建VAR模型检验我国资产价格对货币政策的反应以及资产价格对货币政策目标的影响,发现资产价格、货币政策及货币政策目标间存在长期协整关系,资产价格对产出有正向冲击作用,股市显著影响通货膨胀,但房地产市场对通货膨胀推动作用不明显,资产价格受货币政策的冲击影响显著,其中股市对货币政策冲击的反应明显大于房地产市场.     

金融冲击与房地产市场波动*——一个宏观分析框架及中国的经验证据

本文从总量宏观分析的视角,提出了金融变量与房地产市场的“总体冲击—传导机制”假说,据此用中国的数据构建金融状况指数（包含房价的FCI1和不包含房价的FCI2）,再对金融状况指数（FCI1和FCI2）与房地产指数做实证分析。研究发现,在资产价格中房价比股价更能反映一国的金融状况;在引入金融状况指数的金融变量中,利率与房价的相关性最强;房价和利率对总产出的影响周期更长。国房景气指数、房地产投资指数和房价指数对FCI冲击的响应显著,并存在不同的表现。由于房价对居民财富、金融状况和宏观经济的影响显著,货币政策理应干预房价,必须精准把握干预的时机和干预的力度以及注重多种货币政策工具的有效搭配使用。     

流动性约束与货币政策的资产价格效应

本文在新凯恩斯主义分析框架下,基于一个动态随机模型探讨了代理人消费流动性约束下的货币政策的资产价格效应,得到下列结论：资产价格波动通过财富效应影响代理人的消费。以利率为操作目标的最优货币政策应对股价、房价等资产价格波动做出反应,而其反应强度依赖于受流动性约束的代理人所占的比重。由于资产价格波动导致了流动性约束的时变性,最优利率规则对股价、房价等资产价格波动的最优权重也具有时变性。本文的实证分析表明,我国央行对房价和股价波动的利率调整具有时变性,以及此次金融危机爆发期间显现的这种时变性特征,与本文理论分析结果相吻合。     

货币流动性对中国资产市场的冲击效应研究——来自1997—2010年的经验证据

金融危机后,中国实施了积极的财政政策和适度宽松的货币政策,虽然经济实现了快速复苏,但资产价格上涨的压力也再度显现。实证研究结果表明,货币流动性与我国资产价格之间存在单向的格兰杰因果关系,脉冲响应函数结果也显示,流动性过剩后一般会出现资产价格上涨,尤以房地产市场和股票市场的脉冲响应较为明显,债券市场的脉冲响应相对不太显著。     

Stochastic and structural fiscal policy in a monetary stationary economy

In the framework of a monetary asset pricing model which is simple enough to generate closed form formulae for equilibrium price functions the interactions between output, fiscal policy, and asset markets is investigated. With money yielding liquidity services in the exchange process real stock prices are negatively correlated with anticipated (stochastic) fiscal policy changes, while the impact of unanticipated (structural) fiscal policy on the stock market depends qualitatively on the ‘business cycle’ of the economy. It is shown that the monetary character of the economy, more precisely the role of money in the exchange process, is critical for the relationship between fiscal policy and real share prices. Moreover, while contingent fiscal policy measures may be successful in stabilizing the real interest rate on money they are incapable of achieving a stable term structure of the real rate on stocks. In contrast, uncontingently higher public expenditures generally promote the volatility of the real rates on financial assets.     

Structural Changes and the Scope of Inflation Targeting in Korea *

A small, open macroeconomic model that accounts for new financial accelerator effects (the effects of fluctuations in asset prices on bank credit and economic activity) is developed to evaluate various policy rules for inflation targeting. Given the conditions of asset markets and the fragility of the financial sector, monetary policy responses can potentially amplify the financial accelerator effect. Simulations are used to compare various forms of inflation targeting using a model that emphasizes long-term inflation expectations, output changes, and the asset price channels. The simulations suggest that a successful outcome can be obtained by adhering to simple forward-looking rules, rather than backward-looking policy rules. Furthermore, inflation targeting can contribute to price as well as output stability by helping to keep the financial accelerator from being activated. Inflation targeting in emerging economies can provide an environment conducive to long-term capital market development. [E51,F3,F4]     

Macroeconomic Effects of Asset‐Price Shocks in a Globalized Financial Market

In this paper, I study a model in which shocks to asset prices affect the real sector of the economy through a credit channel. As financial markets become internationally integrated, the economy becomes less vulnerable to domestic asset‐price shocks, but more vulnerable to foreign asset‐price shocks. To the extent that monetary policy stabilization is feasible and desirable, the globalization of financial markets shifts the focus of monetary policy from domestic asset prices to worldwide asset prices.     

Real estate prices and systemic banking crises

The collapse of real estate prices has historically jeopardized banking stability and triggered systemic banking crises. This paper studies risk contagion in a banking system in real estate price shock by adopting complex network theory. Modelling the real estate-related asset as a common exposure of banks to the real estate market, we propose a model that incorporates two main risk contagion channels, i.e., the financial network and asset fire sales, and reveal how the real estate price shock is transmitted and propagated across banks. We demonstrate that banking stability is highly sensitive to the real estate price shock. Moreover, due to the particularly low liquidity of the real estate market, the asset fire-sales of real estate assets overwhelms the financial network, playing the dominant role in risk contagion. Our model can be adopted by regulators to conduct stress testing and to forge effective risk management strategies.     

Global Determinants of the Gold Price: A Multivariate Cointegration Analysis

The present paper follows publications which have investigated the influence of global liquidity developments on commodity prices and asset price indices. It contributes to the literature by analyzing how global developments in money, output, and inflation can be related to developments in gold prices in a long‐run perspective. Applying a multivariate cointegration (CVAR) analysis, this study investigates long‐run relationships between these variables. The results suggest a significant influence of excess global liquidity on real gold prices and a co‐movement of real gold prices and global inflation.     

How the Machinery of International Finance Runs with Sand in its Wheels

The dramatic swings in international capital movements in recent years have renewed interest in restrictions on capital flows. This paper provides a model of international asset flows and domestic equity price formation incorporating three restrictions on capital flows. A transaction tax introduces significant asymmetries in the reaction of asset prices to financial and real shocks but has no long-lived effects. Policies targeted to the level of net foreign debt by imposing a tax or outright controls do influence the steady-state levels of the real exchange rate and relative equity prices.     

Monetary policy and exchange rate dynamics in the Spanish economy

As the Spanish economy gets more integrated in international markets, the real exchange rate becomes a key determinant of the monetary transmission. In this paper we trace out the dynamic response of prices, output and the exchange rate following a monetary policy shock. We estimate a structural VAR model whose identification scheme is based on the long run properties common to a large class of models. The results suggest that a small model with efficient asset markets plus nominal inertia and long run monetary neutrality, captures the essential features of the monetary transmission mechanism in Spain. The interest rate shock is well identified and the exchange rate overshoots its long run value. There are no signs of liquidity puzzle nor of price puzzle or exchange rate puzzle either.     

Impact of asset price fluctuation on China’s monetary policy: An empirical analysis based on quarterly data, 1994–2006

The strenuous fluctuation in global asset price in recent years has had a profound impact on the economic and social development of every country. An empirical analysis indicates that asset prices (the stock price index and real estate prices) are important endogenous variables affecting the interest rate reaction function of central bank monetary policy. With expected inflation as a given, each one percentage point rise in output gap will cause a 0.79 percentage point reduction in interest rates by the central bank and each one percentage point rise in real estate price will result in a 2.2 percentage point rise in interest rates. The stock price index does have an influence on the trends in monetary policy, but it is less salient than the impact of housing prices. We also show that monetary policy that employs asset price as an endogenous variable increases the central bank’s control in seeking to attain its objectives. Therefore we suggest that the central bank should make asset price fluctuation an endogenous variable and incorporate it into its forward-looking interest rate rule, in order to facilitate the healthy development of China’s markets for real estate, stocks and derivatives, energy and bulk commodities and maintain rapid, smooth, sustainable and harmonious economic development.     

中美货币政策变动与国内资产价格调控

后金融危机时代,美国持续量化宽松货币政策所带来的溢出效应已对中国资产价格调整产生实质性影响;美国货币政策变动后可通过利率和国际资本流入进行传导,能直接引起中国股票市场价格的剧烈波动并间接推动房地产价格的上涨;在中国房地产市场正处于深度调控背景下,美国货币政策的进一步放宽将对中国货币政策的适度紧缩形成强烈制约,使中国资产价格调控面临巨大的风险和隐患。     

Assessing macro-financial linkages: A model comparison exercise

The recent global financial crisis has increased interest in macroeconomic models that incorporate financial frictions. We illustrate the simulation properties of five medium-sized general equilibrium models used by central banks in the Eurosystem. The models include a financial accelerator mechanism (convex “spread” costs related to firms' leverage) and/or collateral constraints (based on asset values). We provide results from impulse responses to shocks originating in the financial sector as well as a monetary policy shock. Overall, the models share qualitatively similar and interpretable features. This gives us confidence that we have some common understanding of the mechanisms involved. Finally, we survey recent trends in the literature on financial frictions.     

Liquidity shocks: A new solution to the forward premium puzzle

The frequent empirical failure of uncovered interest rate parity raises a question that has not been definitively answered: why do predictable excess returns on currencies persist in competitive currency markets? Supported by data from nine major currencies for 1978:08–2019:09, I provide a novel resolution to this enduring forward premium puzzle by building on the financial economics literature that explores the economic implications of limited access to capital markets. A liquidity shock, or the urgent demand for liquidity by credit-constrained arbitragers liquidating bond holdings, causes losses from sudden drops in bond prices. Arbitragers require a liquidity premium to compensate for potential losses that vary directly with the interest rate. It is this liquidity premium that explains persistent excess returns on currencies. I argue for policies favoring a low interest rate environment and macroprudential controls that ease liquidity constraints to increase the efficiency of international capital markets by reducing the liquidity premium.     

Monetary policy and asset prices

The purpose of this paper is study the effect of monetary policy on asset prices. We study the properties of a monetary model in which a real asset is valued for its rate of return and for its liquidity. We show that money is essential if and only if real assets are scarce, in the precise sense that their supply is not sufficient to satisfy the demand for liquidity. Our model generates a clear connection between asset prices and monetary policy. When money grows at a higher rate, inflation is higher and the return on money decreases. In equilibrium, no arbitrage amounts to equating the real return of both objects. Therefore, the price of the asset increases in order to lower its real return. This negative relationship between inflation and asset returns is in the spirit of research in finance initiated in the early 1980s.     

Credit policy and asset price bubbles

In this paper, we study the effectiveness of credit policy to stabilize the economy after a bursting asset price bubble. We estimate a DSGE model with an asset price bubble for the United States. We find that credit policy does stabilize the economy in response to a bursting asset price bubble. However, credit policy is less efficient in response to the bubble compared to a capital quality shock. The stabilizing effect on output is only roughly 30% for a bubble shock compared to a capital quality shock. Further, while credit policy increases the recovery speed for a capital quality shock it does not affect the recovery speed after a bursting bubble. We also find different dynamics under a binding zero-lower bound, but our previous qualitative findings remain unchanged.     

What do capital inflows do? Dissecting the transmission mechanism for Thailand, 1980–1996

This paper examines the effects of private financial (non-FDI) capital inflows in Thailand in the pre-crisis period (1980:I–1996:IV). Private capital inflows are found to be associated with higher asset prices, lower lending rates, surges in bank lending and domestic spending driven by higher investment, higher output, modest inflation, and modest real exchange rate appreciation. Inflows are also associated with a greater vulnerability to a liquidity crisis, but not with greater external solvency risk. Current account deficits are temporary, thus sustainable, as exports catch up with higher imports within two years. Consequently, the Thai crisis appears to be more of a liquidity crisis than an external solvency crisis.
